I actually already have downloaded that database and followed all the steps in the getting started guide except for the payment gateway. I'm working on my application for that right now. Do I just need a payment gateway to finalize the process?
Currently, when I test it I just get to the end of the order and when I click submit, it just takes me to a broken link. I want to know how to change it so that it accepts the order and takes them back to where they were.
